Delaware Application June Pa., a .Y corporation of 16, 1936, Serial No.85,562'

4 claims. (C1. 15-'3'5) This invention relates to shoe polishingmachines, and more particularly to that type of shoe polishing machineshown in my copending application Serial Number 82,100, filed May27,1936, for Shoe polishing machine, wherein a polishing andpolish-applying brush has a planetary movement about a foot-rest.

In this type of shoe polishing machine the extra polishing brushlnecessary for the tip of the shoe, and more particularly the upper partthereof, must necessarily have an oscillatory movement in order that itmay clear the planetary brush as it moves about the shoe.

Considerable difficulty is met with in securing a proper burnish` vforthe shoe tip, as the brush in its oscillatory movement has a tendency toskip the edge portions or sides of the shoe and leave the sameinsuiiicientl'y burnished. Furthermore, with theo'rdinary constructionthe oscillationv is necessarily more or less rapid, further decreasingthe chances of proper burnishing. l

An important object of this invention is Vthe provision of anarrangement whereby the tip burnishing brush may be moved across the tipof the shoe very slowly and be caused to dwell at that side of the shoeat which the bristles or ber of the brush tend to separate from the shoedue to the ldirection of yrotation of the brush, and more specificallythe provision of an arrangement whereby the return movement of the brushcan beV made extremely rapid thereby enabling the greatest possiblepolishing time to be utilized.y

Another object of the invention isY the proviparts may be arrangedwithin the smallest possible compass and at the same time be durablyconstructed so that they may operate eliciently through a considerablevperiod without continual attention. v Y

'I'hese and other objects I attain by the construction shown in theaccompanying drawings wherein, for the purpose of illustration, I haveshown a preferred embodiment of my invention and wherein:

Fig. l is a perspective View of the interior mechanism of a shoepolishing machine constructed in accordance with my invention;

Fig. 2 is a sectional view on line 2-2 of Fig. 3; Fig. 3 is a section online 3-3 of Fig. 2; and

Fig. 4 is a section on line 4-4 of Fig. 2.

Referring now more particularly to the drawings, the numeral I generallydesignates an inclined platform from which perpendicularly extends astandard I I. This standard is surrounded by a rotatable unit I2 insubstantially all respects identical with that described in thecopending application above referred to and has at its upper endafoot-rest I3. The rotatable unit includes an oscillatable arm I4bearing the brush shaft I5 having a polishing and polishapplyingplanetary brush I6 secured thereto. The shaft of this brush is guidedthrough a slot formed in' a disc IBlikewise. forming a part of therotating unit for in-and-out'movement to enable it to accommodateitselfto the contour of thefoot-rest and this in-and-out movement issupplied by a cam I9 attached to the foot-rest. The brush-bearingarm I4`is constantly urged inwardly by a spring |9a' connecting this arm with(the hubf the unit I2 surrounding the standard II. Polish is supplied tothe brush I6 through a distributing shield 20 Vsuch as described in saidcopending application 'and the distribution of 'polish-lto'this shieldfrom the polish container 2| is obtained through' an intermittentlyoperating mea'suringv force pump 22 actuated by a gear-cam "unit 23driven fro'mthe unit I2, said force pump being supplied by a circulatingpump 24. lThese elementsVv are all substantially as described in thesaid-copending application and form no part "of my invention except inthe combinationashereina'fter set forth. v

' The rotatable unit is driven through a motordriven belt'25 and a Wormshaft 26 cooperating with-a worm gear'21 forming a portion of the unit,suchbelt 25likewise driving a shaft 28 mounted in bearings 29 carried bythe rear end of thev inclined platform I0. Y Aligned with shaft 28 andmounted in bearings 3|] 'for oscillation is an'oscillatory'shaft 3|',said shaft v3| having secured thereto a yoke 32 mounting a stub shaft33. Oscillatable about the stub shaftis a standard 34 theupper'end'offwhich rotatably mounts a brush shaft-,335' having" the toeburnishing brush 36 secured thereto. Rotatable upon the stub shaft 33isa combined friction disc and pulley 31 the pulley element of which isconnected with a pulley 38 on brush-shaft 35 by a belt 39. Shaft 28 hasa spring-pressed friction disc 4I) for co-action with the friction discof element 31. Likewise mounted upon and secured to the oscillatoryshaft 3| is a unit comprising arms 4| and 42, the arm 4| being connectedto the platform by the spring 43 and the arm 42 having an adjustablestop 44 directed therethrough for engagement With the platform so thatoscillation of shaft 3| under action of spring 43 may be adjustablylimited. f

Slidable upon the oscillary shaft 3| is a collar 45 engaged by a fork 46pivoted at 41 to the platform and having its opposite end co-acting witha cam 48 secured to the under surface of the gear 21, a spring 49maintaining engagement of the cam and shifting fork. This collar haspivoted thereto one end of a link 50, the opposite end of which ispivoted to the standard 34 and it Will be obvious that as gear 27 isrotated the cam 48 will cause the standard tov oscillate to and fro inthe direction of the arrow A of Figure 2. Yoke 32 has an arm 5I pivotedto one end of" a thrust bar 52 the opposite endv of which is forkedstraddling the rotatable unit l2 above the gear 2,1 and having a roller53 col-acting with a cam 54 secured to the unit; Thiscam will obviouslycause longitudinal reciprocation off the Y thrust arm 52 and,accordingly, oscillation of the standard 34 about the shaft 3l as apivot and in the general direction of the arrow B of- Figure l. Cams 48and 54 having the proper conformation and being properly disposed asregards the' unit I2, it will be obviousl that the brush standard may beoscillated to elevate brush 36- out of the path of movement ofthe brushI64 and-since this elevation can'be rapidly effected, it can be delayeduntil the last possible moment. This enablesthe burnishing brush todwell in itsv engagement with the shoe tip at the far side of the shoeor at the limit of its movement sothat a proper burnishing of thisportion of the shoe may be obtained. 'I'he cam 54'will, of course,suddenly release the standards, enabling the same to bereturnedimmediately to its polishing level by the spring 43. Cam 48 will serveto control the speed of movement of the burnishing brush across the tipof the shoe and since the engagement with the shoe is determinedby thespring 43 the pressure applied by the brush may be very closelyregulated at all times.

The drive employed-for the planetary brush is substantially a duplicateof thatfillustrated in the application above identied.Itcomprisesafriction disc 55Y co-acting with friction disc 56 upon shaft26 and having a pulley 51 driving acompound pulley unit 58 rotatablymounted upon the unit I2. Suitable belting connects this pulley -unitwith the shaft of the planetary brush.

Since the construction illustratedv is obviously capable of considerablemodicationwithout materially departing from the spiritV of my invention,I do not wish to be understood as limiting myself thereto except ashereinafter claimed.
